Former Welsh star Gavin Henson faces a fitness battle to make the season opener against Treviso on Saturday.

Dragons could face a halfback deficit as flyhalf Henson and scrumhalves Tavis Knoyle and Rhodri Davies all have late fitness tests ahead of the Guinness PRO14 league opener with Benetton Rugby at Rodney Parade on Saturday (KO 7.35pm).

The 36-year-old managed 15 appearances and scored 98 points for the Dragons last season despite facing a number of injury setbacks throughout the campaign.

Henson joined the Dragons in the summer of 2017, after signing a two-year deal to return to Wales from Bristol RFC.

The British and Irish Lion, who toured in 2005 to New Zealand, achieved Grand slams with Wales in the Six Nations Championship in 2005 and 2008.
